To all whom t may'concem: V

Be it known that l, Jol-IN GcFninnno, a citizen of the United Maiden Rock,'in the-county of Pierce and State of lVisconsin, have inventada new and useful Improvement in Tire- Chains, of which the following is a specification.

This invention relates to tire chains for preventing the slipping or skidding of wheels of an automobile or motor vehicles and is particiilarly adapted to gripping devices ywhich use chains across the tread of the tire.

The object of the invention is to provide a simple and ettective means for holding the cross chains .in place, spaced apart.

A further object to hold thccross chains by n'icans which allor-ds easy replacement of new cross chain Wl'ien'the 'old one is worn ont or broken.

It is also an object to have the cross chain holding,` means formed in two parts which are held together byy Snaps or other suit 'able means, the object being to apply one half of the chain to the wheel or tire at a time, snapping the ends ofthe saine'around the spokes or' the 1wheel, then turning the Wheel into a position Iso as to apply the other half of the chain.

"With these' objects in View, and also others which will be` hereinafter more clearly delined and set forth in the claims, in the ac companying drawings forming a 'part of this specificatlon l Figure l 1s a side elevation of a pneumatic tire 'part of Which .is broken away illustrating the improved tire chain attached theretot lig. 2 is a detail view of a portion of the chaine4 Fig; 3 is a lperspective view of a detail portion of the chain.

Fig. 4L is a crosssection of the tire illus-V trating the chain attached thereto.

In the drawing, A represents a holding ring which is composed of a series of llnks B which are freely connected together. 'lvvo rings A am used to (make up the tire' chain,

tire and the other on the other side. The

rings .A are adapted to hold the cross chains C.

The links B are Jformed of wire' orany suitable material and have a slightly curved portion or long arm 1 which is formed with aneye 2 on one end, loop 3 on the other end and a short arm 4 extending at right angles States, residing at .links to the porltion 1 from the .loop 3, the arms 4 having h ooks or eyes V5 formed on their ends. It is an important :Feature that the links B which are formed with eyes2, loops 3, arms d and hooks or eyes 5 are formed'fro'm one piece of Wire or other suitable material.

lfhe hooks 5 are adapted to hold the cross chains C 1n spaced apart position as illustrat-ed 1n Flgs. 1 and 2 and can be bent open as 1s illustrated in the dotted outline inFig. 3. Thus should it be necessary to put in a nen7 cross or gripping chain C, it can be easily and quickly accomplished bvopening the hooks 5, inserting the ends ofl in the m The eyes 2 are adapted to freely engage in the loops 3 of the adjacent link; thus forming a complete licxible ring A; on either side of the The portion l of links B being stiff and extending from one cross chain holding arm to the other, serve to hold the cross chains in 4position much better than if the links B made up of a hooks and again closing the same.

against the run ofthe wheel, as is illustrated in Fig. 4

The chain is made n two semi-circular parts, D and E which .are connected together by means of snap hooks 8 or any other suitable means. The portions D or E of the chain can be attached inde endently of each other to the' tire and wheelx.) advantage if one finds it necessary to attach the chains While the tires are in the mud, as it allows one half of the chain to be attached to the wheel and then by turning the wheel half way around, Vthe other half can be a plied to the wheel and' at the saine timepulling the vehicle out of the mud.

The forming of the linksB in one piece simplifies the construction of thetire chain and allovjs the replacement of any link very easily.

'While one form and constrnction of device has been described and shown, I desirel to have it nndcrstood that this is only illustrative and the invention can be carried out by other means and applied to other uses with in the scope of the following claims:

1. vIn a' tire chain.l comprising', a seriesl of formed from 4a single piece of Wire, each of said links being formed with an eye the chain` were formed of flexible chain This is al great one one end, a looy on the other end, an arm extending outwardly approximately at right angles from said loop and a hook formed on the outer end of said arm, the eye of each link being connected to the loop of the ad jacent link to forrn a continuous ring on either side of a tire and eioss chains adapted to be connected to said hooks, Substantially as described.

2. In a tire chain comprising, a series otlinks formed from asingle piece of mate rial, Said links being bent to .formaV loop, e long and a short arm extending from Said loop and approximately at ri ht angles to each other and an eye forme on 4the end ot each, of said arms whereby the eyes formed on the ends of Said. long arms are adapted to connect inthe loops of the adjaeent links to form a holding ring on either side of a tire and the eyes on Said Short arms connect with ille loop of the adjacent linlr to form :L ring on either side of a tire and. the Short-arm which extends at approximately right angles outwardly, from said ring being curved so as to be spaced away from the rim of a. tire and the eye on said short arm connecting with cross chains which forni gripping ineans over the tread of' tire.
